What do 2H, 4L, and 4H represent in 4WD vehicles?

[Dale]

2H stands for two-wheel drive, 4H is the four-wheel drive high-speed mode, and 4L is the four-wheel drive low-speed mode. Here is some additional information: 1. Usage scenarios for 4H and 4L modes: If driving through snow or slippery surfaces, the 4H mode is highly suitable as it ensures sufficient drive wheels while preventing excessive driving force that could cause wheel slippage. Due to its high driving force, 4L is not suitable for such conditions but can be used when climbing steep slopes or off-roading to maximize vehicle power. 2. Usage scenario for 2H: High-speed four-wheel drive is not suitable for highway driving. For part-time 4WD vehicles, dry paved roads are not appropriate for 4H or 4L modes; only the 2H mode should be selected.
